Update: Trailered the tractor to the dealer. They are going to look at the oil leak and inspect the harnesses for damage. I'm not confident the dealer's service is going to be thorough or effective. This dealership is not primarily in the business of selling tractors. I knew that going in, but I also had conversations with the technicians and felt confident. After my interaction with the service manager, not so much now.
We will see what happens when I get the tractor back. I used it a fair amount last weekend and had no issues with stalling or fuses. It's a really useful tool and I am not regretting my purchase. LS makes a quality tractor. I think the dealer prep and support is my trouble here.
